Established in 1975, our ISO/IEC 17025 accredited laboratory serves conductor manufacturers worldwide as an independent third-party testing partner, with over 50 customers qualified across 30+ countries. Testing is performed to IEC, IEEE, ANSI and other applicable international standards, covering the full spectrum of
mechanical, electrical, thermal and vibration performance.
Tested here. Trusted everywhere.
A transmission line is only as reliable as the proof behind it. Before a conductor enters service anywhere in the world, its performance must be demonstrated, measured, documented and verified by a laboratory the industry can rely on. That is the role TAG has served for five decades, an impartial testing partner whose reports carry weight with utilities, contractors and manufacturers alike.
Tensile strength (UTS), stress strain behaviour, creep and elongation, and stranding integrity testing for conventional and HTLS conductors.
(Electrical Resistance, High Current and Thermal combined): DC resistance measurement and current carrying capacity verification, with thermal cycling under sustained high current up to 4,000 amps, verifying conductor performance and joint integrity across repeated heating and cooling cycles.
Corona onset voltage, radio interference voltage (RIV), and dielectric withstand testing under high voltage conditions.
Aeolian vibration endurance testing to determine conductor and fitting fatigue life under wind induced oscillation.
Environmental exposure testing including salt fog chamber qualification for corrosion resistance.
